I also wonder about peoples water changing regiments. Jared and I are going to be building a pond this spring, so i'm trying to plan before hand if I need some sort of a drain setup. Luckily I have a swail on the edge of my property right behind the pond, so drainage will be easy.

How often do you change water? Or do you even change water?
